Note the purpose here is to make it simpler to add more subcommands, without adding a lot of things to Driver. This creates a copy of CodegenOptions, but it was double-registered at present which felt odd. It's also fairly small right now. If this becomes an issue, maybe we can look into using optional for delayed initialization, or just go back to straight sharing. --------- Co-authored-by: josh11b <15258583+josh11b@users.noreply.github.com>
